Impedance spectrum of a classical flute with a flared foot measured at the embouchure hole using fingering for F5. Z is plotted in dB, i.e. 20 log(Z/Pa.s.m-3).

This fingering uses a key to open a hole, rather than raising a finger, but the acoustical difference is unimportant.

How were these results obtained?
Acoustic measurements are available for these flutes -
modern B, modern C, classical C, classical D, classical flared, baroque
Sound clips are available for modern B, classical flared and baroque		 To compare flutes, it is easiest to open a separate browser window for each instrument.
